How does that imply we're better? It implies we have the ability to possess ethics. At no point did I say possessing ethics made one superior to a being that couldn't.
Can you tell me which animals have been able to:
Have ethics
Create life saving technologies that can prolong the life of animals
develop transportation capable of leaving this planet
develop the technology to communicate and coordinate with other members of the same species across the planet instantly.
create irrigation systems that can benefit the whole of the species and that of other species
take endangered species in, protect them, and try to cultivate their population numbers for the extension of that species' existence (you conveniently fail to mention that humans do this, where no other species does it)
develop ever evolving methods of education to improve the proficiency of the species as a whole?
Undertake the kind of assistance to other members of the species like the red cross, doctor's without borders, etc. On a regular basis, humans take time out of their lives to try to benefit others, where in most animal populations they live by survival of the fittest, and tend to their own family unit. Many species will leave injured and weak members of their own species to die (I know some species offer support but they're a minority)
I can go on and on, but as far as species go, in good cases and bad, no species is as superior thus far in sheer accomplishments and abilities than humans.
It's one thing to say that no life is more valuable than the other, kumbayah and all that ****, but to say humans aren't superior to any other species is just silly.
